Description
Technical Field
[0001] This utility model relates to a water dispenser, and more particularly to an outdoor dual-purpose water dispenser. Background Technology
[0002] Water dispensers, as essential equipment in modern life, greatly facilitate people's access to drinking and domestic water. Outdoor water dispensers, especially those installed in public places such as parks, scenic spots, schools, and squares, play an indispensable role in meeting public drinking water needs and promoting public health. Outdoor water dispensers not only solve the drinking water problem for people during outdoor activities but also help reduce the use of disposable drinking containers such as plastic bottles, playing a positive role in environmental protection and resource conservation. With increasing health awareness and more frequent outdoor activities, the demand for multifunctional outdoor water dispensers that can simultaneously provide drinking water and handwashing water is gradually growing.
[0003] In the existing technology, outdoor water dispensers mainly include single-function water dispensers and multi-functional water dispensers that integrate drinking and handwashing functions. Single-function water dispensers typically use a simple activated carbon filtration system, providing only basic drinking water purification. Multi-functional water dispensers, on the other hand, add a handwashing function. Nevertheless, these water dispensers still only use a single or dual filtration system, such as activated carbon or ceramic filters. In addition, these outdoor water dispensers are generally directly connected to the municipal water supply network, relying on municipal water pressure to provide water flow. After preliminary purification, the water is supplied to the drinking and handwashing systems separately after simple diversion, while wastewater is directly discharged into the sewer.
[0004] While outdoor dual-purpose water dispensers offer great convenience, existing equipment also has some shortcomings. Firstly, most outdoor water dispensers lack a complete multi-stage filtration system, failing to effectively remove suspended solids, chlorine, organic matter, bacteria, viruses, and other harmful substances from the water, thus compromising drinking safety. Secondly, the design of the drinking and handwashing functions in traditional outdoor water dispensers is not reasonable, particularly regarding height: the height of the drinking spout and handwashing faucet is often improperly set, lacking clear functional distinction, leading to easy cross-contamination between the drinking and handwashing areas, increasing hygiene risks. Furthermore, the traditional design places the two functional areas too close together, lacking effective spatial separation, making it difficult to avoid cross-contamination during use.
[0005] These problems severely restrict the practicality and widespread application of dual-use outdoor water dispensers, and there is an urgent need for a compact, well-filtered, and rationally designed outdoor dual-use water dispenser to meet market demand. Utility Model Content
[0006] The purpose of this utility model is to provide an outdoor dual-purpose water dispenser that can meet the dual needs of drinking water and handwashing water in outdoor environments. It has the advantages of compact structure, good purification effect and convenient use.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an outdoor dual-purpose water dispenser, comprising a casing, a washbasin, a drinking basin, a handwashing faucet, and a drinking faucet. The washbasin and the drinking basin are respectively installed on the casing. The handwashing faucet is installed above the washbasin, and the drinking faucet is installed above the drinking basin. There is a height difference between the handwashing faucet and the drinking faucet. The outdoor dual-purpose water dispenser also includes a filtration water path and a wastewater pipe disposed within the casing. The filtration water path includes a pre-filter assembly, a reverse osmosis membrane assembly, and a sterilization assembly connected sequentially along the water flow direction. The inlet end of the pre-filter assembly is connected to the raw water inlet. The outlet end of the sterilization assembly is connected to an outlet water diversion system. The outlet water diversion system is used to deliver the purified water to the handwashing faucet and the drinking faucet respectively. Both the washbasin and the drinking basin are connected to the wastewater pipe, and the outlet end of the wastewater pipe is connected to a wastewater outlet.
[0008] Preferably, the pre-filter assembly includes a PP filter element and a CTO filter element connected in sequence. The PP filter element is used to filter large particulate impurities and suspended solids in the water, and the inlet end of the PP filter element is connected to the raw water inlet. The CTO filter element is used to adsorb chlorine, organic matter and odors in the water, and the outlet end of the CTO filter element is connected to a booster pump.
[0009] Preferably, an inlet solenoid valve is provided between the CTO filter element and the booster pump.
[0010] Preferably, the reverse osmosis membrane assembly includes a first reverse osmosis filter element and a second reverse osmosis filter element arranged in parallel. The outlet end of the booster pump is connected to a diversion pipe, which is connected to the inlet ends of the first and second reverse osmosis filter elements respectively. The outlet ends of the first and second reverse osmosis filter elements merge and are connected to the inlet end of the sterilization assembly. Both the first and second reverse osmosis filter elements are provided with wastewater outlets, which are connected to the wastewater pipeline through a wastewater solenoid valve.
[0011] Preferably, the sterilization component includes a UV sterilization lamp and a sterilization lamp cover. The UV sterilization lamp is disposed inside the sterilization lamp cover, and the sterilization lamp cover has a water flow channel so that the water purified by the reverse osmosis membrane component flows around the UV sterilization lamp.
[0012] Preferably, the water distribution system includes a first diversion channel and a second diversion channel, wherein the first diversion channel is connected between the handwashing faucet and the sterilization component, and the second diversion channel is connected between the drinking water faucet and the sterilization component.
[0013] Preferably, the outlet of the booster pump is provided with a backup pipeline, and the backup pipeline is provided with a backup solenoid valve, so that the outlet of the backup solenoid valve can be selectively connected to the handwashing faucet.
[0014] Preferably, both the handwashing faucet and the drinking water faucet are push-button faucets.
[0015] Preferably, the height of the water outlet of the drinking faucet is higher than the height of the water outlet of the handwashing faucet.
[0016] Compared with the existing technology, the advantages of this utility model are as follows: After the raw water enters the system from the raw water inlet, it first undergoes preliminary treatment through the pre-filter component to remove large particulate impurities and harmful substances in the water. Then, the water flows into the reverse osmosis membrane component, where reverse osmosis technology further filters out fine impurities, heavy metal ions, and harmful substances in the water. Finally, the water flows through the sterilization component for ultraviolet disinfection treatment to completely kill bacteria and viruses in the water, ensuring water quality safety. The purified water is then distributed to the handwashing faucet and drinking water faucet through the outlet water distribution system to meet the different needs of users for handwashing and drinking water.
[0017] The outstanding advantage of this design lies in the reasonable height difference between the handwashing faucet and the drinking water faucet, which clearly separates the two functional areas and avoids cross-contamination. In addition, the design of the wastewater pipeline ensures that the wastewater generated during use can be effectively collected and discharged, maintaining the cleanliness of the environment around the equipment. The entire system achieves comprehensive water purification through a combination of multi-stage filtration and ultraviolet sterilization, which not only meets the strict requirements for drinking water safety in outdoor public places, but also takes into account the functional needs of handwashing water.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0023] Example 1: As Figures 1-2 As shown, an outdoor dual-purpose water dispenser includes a housing 1, a washbasin 2, a drinking basin 3, a handwashing faucet 4, and a drinking faucet 5. The washbasin 2 and the drinking basin 3 are respectively installed on the housing 1. The handwashing faucet 4 is installed above the washbasin 2, and the drinking faucet 5 is installed above the drinking basin 3. There is a height difference between the handwashing faucet 4 and the drinking faucet 5. The outdoor dual-purpose water dispenser also includes a water filtration system 6 and a wastewater pipe 7 installed inside the housing 1. The water filtration system 6... The system includes a pre-filter assembly 8, a reverse osmosis membrane assembly 9, and a sterilization assembly 10 connected sequentially along the water flow direction. The inlet of the pre-filter assembly 8 is connected to the raw water inlet 11. The outlet of the sterilization assembly 10 is connected to an outlet water diversion system 12, which is used to deliver the purified water to the handwashing faucet 4 and the drinking water faucet 5 respectively. The handwashing basin 2 and the drinking water basin 3 are both connected to the wastewater pipe 7, and the outlet of the wastewater pipe 7 is connected to the wastewater outlet 13.
[0024] Example 2: Figures 1-2 As shown, unlike Embodiment 1, the pre-filter assembly 8 includes a PP filter element 14 and a CTO filter element 15 connected in sequence. The PP filter element 14 is used to filter large particulate impurities and suspended solids in the water, and the inlet end of the PP filter element 14 is connected to the raw water inlet 11. The CTO filter element 15 is used to adsorb chlorine, organic matter and odors in the water, and the outlet end of the CTO filter element 15 is connected to a booster pump 16.
[0025] In this embodiment, the pre-filter assembly 8 adopts a dual filtration structure, consisting of a PP filter element 14 and a CTO filter element 15 connected in sequence, forming a highly efficient primary purification system. Water first enters the PP filter element 14 through the raw water inlet 11. This filter element is made of polypropylene and has a microporous structure, effectively intercepting large particles and suspended solids such as sand, rust, and silt in the water, thus playing a physical filtration role and laying the foundation for subsequent purification stages.
[0026] The water, after initial purification by the PP filter cartridge 14, then enters the CTO filter cartridge 15. This filter cartridge is mainly made of compressed activated carbon and has a strong adsorption capacity, effectively removing residual chlorine, organic matter, odors, and some heavy metal ions from the water, significantly improving the taste of the water. The outlet of the CTO filter cartridge 15 is directly connected to the booster pump 16. This design ensures that the water flow after the pre-filtering process receives sufficient pressure, providing the necessary power for subsequent reverse osmosis filtration.
[0027] The advantages of this pre-filter component 8 are: on the one hand, it improves the overall filtration efficiency and extends the service life of the subsequent reverse osmosis membrane through the principle of graded filtration; on the other hand, it uses different filter materials for different types of pollutants, realizing the organic combination of physical filtration and chemical adsorption, which greatly improves the purification effect of pre-treatment. At the same time, the configuration of the booster pump 16 solves the problem of insufficient water pressure in traditional outdoor water dispensers, ensuring the normal operation of the reverse osmosis system.
[0028] In this embodiment, a water inlet solenoid valve 17 is provided between the CTO filter element 15 and the booster pump 16.
[0029] In this embodiment, the inlet solenoid valve 17, located between the CTO filter element 15 and the booster pump 16, is a key control component in the entire water purification system, playing a crucial role in regulation and protection. This solenoid valve is located at the connection point between the final stage of the pre-filtration and the booster pump 16. It controls the flow of water via electrical signals, enabling intelligent management of the system operation. Specifically, when the water dispenser is in operation, the inlet solenoid valve 17 opens, allowing water that has undergone preliminary purification by the PP filter element 14 and the CTO filter element 15 to enter the booster pump 16. When the system stops working or an abnormal situation occurs, the solenoid valve quickly closes, cutting off the water supply and effectively preventing excessive internal pressure or potential leakage due to prolonged disuse.
[0030] The significant advantages of this design are: it provides precise flow control capabilities, which can automatically adjust the amount of water entering the booster pump 16 according to system needs, ensuring that the reverse osmosis membrane obtains the most suitable working pressure, and can automatically cut off the water supply in the event of power failure or malfunction, preventing equipment damage or water waste caused by continuous water supply. At the same time, it simplifies the maintenance process, so that there is no need to shut off the external water supply valve when replacing the filter element or repairing the system, which greatly improves the convenience of maintenance.
[0031] Example 3: Figures 1-2 As shown, unlike Embodiment 2, the reverse osmosis membrane module 9 includes a first reverse osmosis filter element 18 and a second reverse osmosis filter element 19 arranged in parallel. The outlet end of the booster pump 16 is connected to a diversion pipe 20, which is connected to the inlet end of the first reverse osmosis filter element 18 and the second reverse osmosis filter element 19 respectively. The outlet ends of the first reverse osmosis filter element 18 and the second reverse osmosis filter element 19 merge and are connected to the inlet end of the sterilization module 10. Both the first reverse osmosis filter element 18 and the second reverse osmosis filter element 19 are provided with wastewater outlets 13, which are connected to the wastewater pipeline 7 through a wastewater solenoid valve 21.
[0032] In this embodiment, the pressurized water output from the booster pump 16 is evenly distributed to the inlet ends of the two reverse osmosis filter cartridges through the diversion pipe 20, realizing parallel water processing. The reverse osmosis filter cartridges utilize semi-permeable membrane technology, which, under the action of pressure difference, allows only water molecules to pass through while intercepting harmful substances such as dissolved solids, heavy metal ions, bacteria, and viruses, separating the water into pure water and concentrated wastewater. The pure water treated by the two filter cartridges merges at the outlet end to form a larger flow of high-quality purified water, which is directly transported to the downstream sterilization component 10. The concentrated wastewater generated is discharged into the wastewater pipeline 7 through their respective wastewater outlets 13 and controlled by the wastewater solenoid valve 21.
[0033] The advantages of this dual reverse osmosis parallel structure are reflected in several aspects: First, it significantly improves the system's water purification output and treatment efficiency, meeting the needs of high-frequency use in outdoor public places. Second, the dual filter design distributes the workload of a single filter, extends the service life of the reverse osmosis membrane, and reduces maintenance costs. Third, when one filter needs to be replaced or maintained, the other can continue to work, ensuring the system's continuous operation capability. In addition, the wastewater solenoid valve 21 enables precise control of wastewater discharge, avoiding unnecessary waste of water resources.
[0034] In this embodiment, the sterilization component 10 includes a UV sterilization lamp 22 and a sterilization lamp cover 23. The UV sterilization lamp 22 is disposed inside the sterilization lamp cover 23, and the sterilization lamp cover 23 has a water flow channel, so that the water purified by the reverse osmosis membrane component 9 flows around the UV sterilization lamp 22.
[0035] In this embodiment, the sterilization component 10, as the final purification stage of the entire water purification system, employs highly efficient UV ultraviolet sterilization technology and consists of two parts: a UV sterilization lamp 22 and a specially designed sterilization lamp cover 23. The UV sterilization lamp 22 is installed at the center inside the sterilization lamp cover 23, which is designed with a water flow channel surrounding the UV lamp. When the water purified by the reverse osmosis membrane component 9 enters the sterilization component 10, the water flows along the channel inside the sterilization lamp cover 23, evenly surrounding the UV sterilization lamp 22. At this time, the 254nm wavelength ultraviolet light emitted by the UV sterilization lamp 22 can penetrate the water and directly destroy the DNA and RNA structure of residual microorganisms in the water, effectively killing bacteria, viruses, algae, and other microorganisms, achieving the final disinfection and purification of the water.
[0036] In this embodiment, the water diversion system 12 includes a first diversion channel 24 and a second diversion channel 25. The first diversion channel 24 is connected between the handwashing faucet 4 and the sterilization component 10, and the second diversion channel 25 is connected between the drinking water faucet 5 and the sterilization component 10.
[0037] In this embodiment, the water distribution system 12 adopts a dual-pipe design, consisting of a first diversion channel 24 and a second diversion channel 25, forming an efficient water distribution network. The first diversion channel 24 is specifically connected to the sterilization component 10 and the handwashing faucet 4, delivering water that has undergone a complete purification process to the handwashing area. The second diversion channel 25 connects the sterilization component 10 and the drinking water faucet 5, ensuring that drinking water also undergoes comprehensive purification before reaching the drinking water area. This dual-pipe design makes the water flow path clear and unambiguous, avoiding the confusion and contamination risks that may result from cross-connections. Furthermore, the independent piping system ensures that each functional area receives the required water flow, maintaining stable water output performance even when used simultaneously.
[0038] In this embodiment, the outlet end of the booster pump 16 is provided with a backup pipeline 26, and a backup solenoid valve 27 is provided on the backup pipeline 26. The outlet end of the backup solenoid valve 27 can be selectively connected to the handwashing faucet 4.
[0039] In this embodiment, the backup pipeline 26 is arranged in parallel with the main filtration channel, and a backup solenoid valve 27 is installed on the path for flow control. Its outlet can be directly connected to the handwashing faucet 4 as needed. This structural design provides two optional water flow paths: one is a complete purification path through the reverse osmosis membrane module 9 and the sterilization module 10, suitable for high-standard drinking water treatment; the other is a quick path that directly supplies the handwashing faucet 4 through the backup pipeline 26, suitable for handwashing purposes with relatively lower water quality requirements.
[0040] The design of the backup piping system 26 offers multiple advantages: the backup path bypasses the reverse osmosis membrane and sterilization component 10, significantly extending the lifespan of these core filter elements and reducing maintenance frequency and operating costs; the system intelligently switches water flow paths via solenoid valves, selecting the appropriate purification level according to actual needs, avoiding over-treatment of handwashing water and saving energy consumption; the backup path provides a larger water flow and faster water output speed, meeting the usage needs during peak handwashing periods and improving the user experience; when the main filtration system requires maintenance or malfunctions, the backup piping 26 can serve as an emergency channel, ensuring uninterrupted handwashing function and enhancing system reliability.
[0041] In this embodiment, both the handwashing faucet 4 and the drinking water faucet 5 are push-button faucets.
[0042] In this embodiment, the push-button faucet is existing technology. Its structure mainly consists of a push-button rod, a spring, and a valve body. Its working principle is simple and reliable: when the user lightly presses the push-button rod, the water flow channel inside the valve body opens, and water flows out immediately. After releasing the pressure, the spring's rebound force causes the push-button rod to automatically return to its original position, and the water flow channel closes, stopping the water flow. This push-button design is simple and intuitive to operate, requiring no complicated procedures to obtain water flow. It is suitable for people of all ages, and the automatic shut-off mechanism effectively prevents waste caused by forgetting to turn off the water.
[0043] In this embodiment, the height of the water outlet of the drinking water faucet 5 is higher than the height of the water outlet of the handwashing faucet 4.
[0044] This layout design fully considers the actual usage scenarios and human posture requirements for different purposes. The higher position of the water faucet 5 allows adults to drink directly without excessive bending over, maintaining a comfortable and natural drinking posture and reducing pressure on the cervical spine and lower back. At the same time, the higher drinking spout position effectively avoids the risk of the user's mouth coming into contact with the bottom of the device, greatly improving hygiene and safety.
[0045] The relatively lower position of the handwashing faucet 4 is more suitable for handwashing operations. Users can more easily place their hands under the water flow to complete cleaning actions such as rubbing and rinsing, while avoiding the problem of water splashing. This staggered design also visually distinguishes the two functional areas. Even without text labels, users can intuitively identify the different functions, improving ease of use.
[0046] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
